To'aZZ whom it may concern Be it known that I, ALBERT E: J onNsoN,

a citizen of the United States, residing at.

Beverly, in the county of Essex-and State of Massachusetts, have. invented certain new and useful Improvements in Machines .for MakingInsoles'; and I do hereby declare the following to be. a.full,,clear, and exact de-. scription of the invention, such as will enable others skilled in the art Ito which it appertains to make and use the same.

The present. invention relates. to machines lnsoles to be used in the IllLIlll-I for making facture of boots and shoes.

The object of the invention isto. produce a machine for performing varioussteps; in; V 71th. th1s-ob1eot in view a feature of the inventlon;

the making of regular welt. insoles. l

contemplates the provision, in .a machine for making lnsoles, devlces for setting the. lip.

order to set the; lip,- the machine illustrated u the lip, by a light spring 14 coiled around the spindle l2 and interposed between a shoulder-1;") formed-by an opening. in the slide 13 and a transverse pin 16 carried by the spindle. During the operation of the machine the hammei is vertically reciprocated-against the'tens'ion of the spring 14:,toset thelip, through an operative connection with a hammer arm or actuator l? mounted to oscillate about a horizontal stud 18 car ried by the knife slide 13. ed, the" hammer actuatoroscillates across the line of feed, or, stated morebroa-dly, moves-I in a path at substantially right angles to the path of movement of the hammer. The hammer is operatively connected to the actua ator 17 by a dog 19 pivotally mounted on a block 20 suitably secured to the lowerend I of. the actuator 17.. The dog 19 is provided with a body portion arranged to engage the upper face of the hammer 9'and with anose 2-1 arrangedto engage awall 22 formed on; the hammer. The nose of the dog is held continuously iei-agaged-with-the wall ofthe hammer by" alight spring23, one end of which is secured to the block 20,*a nd;the other end of which is secured to-the dog 19.

The actuator 17 is connected through-a rod 24; to a cam lever -25pivoted at one end to the machineframe and provided at its otheren'd with a roll engaging a cam groove 26 formed a drum 27 securedto a" driving shaft 28. As the actuator '17 is swung about the horizontal stud 18 to actu ate the hammerthe block '20 is moved down; wardly andv inwardly or toward the-left (viewing Fig. 1), but as the deg 19 is prevented from-.movement toward the left by the engagement of its nose withth'e'wall 22,

the inward movement of the block causes the dog to turndownwardly about its pivotal connectlon with the block against the tension of its spring 23. This movement of the dog actuates the hammer downward so as to strike a blow upon thelip. In order to vary the force of-the blow of the hammer uponthe work, the rod 24c is provided with a turn buckle 29. By manipulating this adjustable 1 connection between the cam groove 26 and the actuator 17, thenormal inoperative posi tionof' the hammer above the wo-rk may be variedlas desired.- As the hammeris-moved downward a uniform distancea variation of fitsrnormal height abovethework eitherva-' ries the force of the blow ofthe hammer upon the work or prevents the hammer from 1 striking the work. 1

.Itis desirable to bevel theedge of the unlippedfaceof a wltinsole-for' a purpose well known to those skilled in the art, and therefore the.present machine has been provided with a bevel-'ing knife which. as shown in Figs. 1, 3 and 5, is securedupon the up-..

.. 5 ;per side ofthe edgegage. 6.. As shown,-theb "the unlippedface of the insole,

*In'bevtling the edge of the unlipped face of an'insole it is highly desirable that the beveling knife act with certainty in removing'theskiving'from the edge of the sole.

To this end the lower end of the beveling knife is'provided with a thin, tapered foot 5 34; (see :Fig. 8) which is interposed. between the sole engaging surface of the worksupport and the unlipped face of the sole The foot 34 maintains the relative position of the edge of the unlipped faceof the'sole andthe cutting edge 33 uniform and thus insures'the complete severance of the bevel string. I 7

- As is wellknown to those skilled'inthe art, because of itscurvature'the lip at the shank is diflicult'to turn up. This difficulty is usually obviated by cutting transverse slashesin thelip at the shank by hand to.

permit the lip turning tool to perform its turning operation upon successive short. sece tions of the lip at the shank. 1 In order? to permit the easy turning up, of the lip at theshank, the feedfootd in the machine of the drawings, is provided with a laterallyv extending knife 35 (Figs-2,3,5 and 6') which,

asthe foot engages the work preparatory to.

the feeding stroke, "cuts a transverse slash.

in the margin of the insole in advance of the operation of the edge'knife 2.' Preferably the depth of the transverse slash is the same as the' thickness" of the 'lip. The slashing knife extends from the feed foot in suchposition that while-the machine is operating around the 'forepart of the sole where the feather isrelativelynarrow', it strikes outside the #edge of the sole when thefeed foot moves downward (see Fig. 5). As'shown in Fig. t the cutting blade of the slashing knife 35 is of such width as to extend only partially across the cutting'edge of the edge knife 2. With this construction, when'the edge gage 6 is set for a narrow feather around the forepart the relation of the sole tothese two-knives is such that while the is rendered inactive. retracted, however, the sole, the movement of the sole inward relative to the 'feed'foot'to retain a bearing against the gage is suflicient to permit the slashing knife to engage and slash'the margin of the sole throughout the shank. The

lip, cut at the shank, is thus divided into-a series of short sections thereby facilitating the operations of turning it up. I

In ordertoavoid weakening the heel seat it is desirable, in channelinginsoles', tos'top I edge knife remains active the slashing knife When the edge gage is to channel the shank of .thecutting of the-knives; ata pointabout opposite the lireast,1line f the-heel. To this end the knife slide '13:,is provided with a rack36 which meshes with; a segment 37 formed onone 'end-o f -an arm 38'pivoted on the machine frame. The other end of the arm 38 is connected to a rod 39 having a'lost motion connectionwith a rod 40' connected to a tread le -;41 pivoted on the machine frame. The lost motion connection between gthe rods 39 and .40 consists of a block 42 (F'gQIQ) secured. to the-rod39 and loosely embracingthefrod 40., The upper end of the 'rod 40 is providedw ith -a set of adjusting and locknuts 43 which -;se rve-to limit the amount of lost motion .in theconnecti'onbeftween'the rinses) and 40. The treadle is also connected to the"work support 5 by a chain 44, one end=of which is attached to the usual work support lowering toggle, and-the other end "of which" is: attached to the treadle 41. Afewlinksofthe chain are normally held slack by coiledfspring 45 ,the opposite ends of which are 'secured'to separated links of the' ehaintFig; 2). The knife slide is thus relieved "offthe' weight of the treadle and the'r'od'4O which permits the'use of a light spring forholdingtheknives to their work and thep'roduction'of a uniform thicknessyof'fchannel flap and flip, WV'ith the constructiondescribed, l'whenit is desired to stop the cutting of the knives, the treadle is depressed I until the lower nut 43 rests upon the bl'ock42; This mowementfof the treadle elevates the kn fe slide; slightly, at the same time str'aingt'ening' the chain 44"w'ithout,

however, lowering thew'qrk support. As the knives areemb'e'ddedin the work,"the insole is raised from the work-support when the "knife slide'isj elevated. Thefeed' foot 4 now 'desce'nd'sf under '-t11e pressure "of its spring'and digs into'the' insole'preparatory tofafeeding step; Owing to-thejho'ldof the knives in the work, the 1? insole" is preventedfroni being stripped from the "knives ufndehthia pressure offthe feedfoot spring. This is r'epresented"graphically in Fig. 7 where the "arrow Ai' represents the pressure of thefeedfoot spring 114"and' the arrow B represents "the'pressnre 'of thefeed" foot in feedihg the insolefor t he cut of the knives. During thefeedthe feed foot spring con.- stan'tly tends 'tofverti'cally depress the insole while the "feed foot is moving the insole" in a horizontal plane. 'T he're sultant of the 'presures A" and *is "represented graphicallyby thearrowC in Fig; 7. l'lhefknives are thus causedto' leave the' Work diagonally-in the'llineof feed ('Fig; f6), whenever the knife slide is' elevated in 'the manner described; {A further'depression of the treadle now completes the-elevation "of the knife slide and 5 simultaneously lowers the work support-to" permit the" ready-removal of the finished insole and the insertion of a fresh blank.

From the foregoing description it be obvious to those skilled in the art that the feature of the invention which contemplates improved mechanism for cutting out the knives is adaptedforuse in ma kingthe leather bodies of insoles intended for-reinforc'ement whether the machine is' -fitted; for makingone or two lips. It will also be obvious that the feature of the invention which contemplates the setting of the ,lipis notdependent for its usefulness on a' combination with lip forming devices, but can be employed in setting the lip of a previously channeled insole.

It will be clear to those skilled in this class of machines and with the general objects of the present invention in view, that changes maybe made in the details of structure, the dr scribed and illustrated embodim'ent of the invention being intended as an exploitation'of its underlying essentials the features whereof are definitely stated in their true scope in the claims herewith.
